Whatsoever things they know not (οσα ουκ οιδασιν). Here 2. Peter 2:12 has εν οις αγνοουσιν. The rest of the sentence is smoother than 2. Peter 2:12.

Naturally (φυσικως). Here only in N.T. 2. Peter 2:12 has γεγεννημενα φυσικα. Jude has the article τα with αλογα ζωα and the present passive φθειροντα instead of the future passive φθαρησοντα.
